Supported Rollup Frameworks

Alchemy Rollups supports multiple rollup frameworks. This guide provides an overview of each framework to help you choose the best option for your project.

Optimism OP Stack

• Overview: An open-source optimistic rollup framework designed for Ethereum equivalence.
• Key Benefits:
  • Low fees and high throughput.
  • Security through fraud proofs and reliance on Ethereum for data.
  • Full EVM compatibility.
  • Superchain, a network of chains that share bridging, decentralized governance, upgrades, a communication layer and more.
• Use Case: Ideal for projects looking for a balance of performance and compatibility.

Arbitrum Nitro (Orbit)

• Overview: A robust optimistic rollup with enhancements for performance.
• Key Benefits:
  • Ultra-low transaction fees with options for even lower costs through alternative data availability models.
  • Fast block times and efficient batching.
  • Full EVM compatibility, with optional support for additional smart contract languages.
  • Interoperability with other chains in the Arbitrum ecosystem.
  • Stylus, which will allow you to write smart contracts in a more performant VM with Rust, C++, or other languages that can compile to WASM. These contracts can interoperate synchronously with the EVM.
• Use Case: Best suited for high-throughput applications with diverse transaction requirements.

zkSync ZK Stack

• Overview: A framework for building ZK-Rollups using zero-knowledge proofs.
• Key Benefits:
  • Instant finality due to cryptographic proofs.
  • High scalability by posting only proofs and minimal data on Layer-1.
  • EVM compatibility with a few potential limitations.
  • Security based on cryptographic guarantees rather than challenge periods.
• Use Case: Ideal for applications that require fast withdrawals and enhanced scalability.
